In Part 1 of this five-part series, we examined FET voltage controlled resistors, basic voltage controlled resistor circuits, and a balanced or push pull voltage controlled resistor (VCR) circuit.

A small, simple AM receiver project with only 3 transistors. This circuit can pick up medium wave stations in your area. It can use general purpose transistors, and in this example there are 3 BC109C ...

Download this article in PDF format. Determining the resistor values and assuring performance of the circuit associated with a photocoupler (also called an optocoupler or optoisolator) is simple in ...

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in series ...

As our economy continues to drive the emergence of energy-efficient systems such as hybrid and electric vehicles, composite aircraft, and wind turbines, the need for power resistors has expanded.
